A microstrip fed broadband dielectric resonator antenna is proposed. The antenna is composed of seven dielectric resonators, a microstrip feeding line and a SMA connector. The seven rectangular dielectric resonators were arranged in the log-periodic way and proximity-coupled to the microstrip feeding line. This approach allows to widen the matching bandwidth. The impedance bandwidth (VSWR ≤ 2) is from 5.19–17.14 GHz with a ratio of about 3.3:1.

In this paper, a novel reflective metasurface is designed to generate a circularly polarized orbital angular momentum (OAM) vortex wave in radio frequency domain. Based on the basic theory of reflectarray antenna, the radio beams carrying OAM with a specific topological charge is produced by individually controlling the reflective phase of each element. The feasibility of the proposed design is verified by the simulated far-field radiation patterns and near-field phase distributions. The reflective metasurface gives an effective way to generate OAM with its advantages of high efficiency and low profile in the radio communication systems.

A broadband dual-polarized magneto-electric dipole antenna excited by Γ-shaped strips is presented in this communication. The proposed antenna contains three parts. The radiating element of the proposed antenna is a combination of the vertically oriented shorted patch, the planar dipole and the bottom plate. The two orthogonal Γ-shaped feeding strips connected with 50 Ω SMA launchers are used to excite the proposed antenna. The corner reflector can effectively improve the radiation performance of the proposed antenna. As shown in simulated results, the impedance bandwidth of the proposed antenna is 48% for standing-wave ratio (SWR) 2 (0.86–2.47 GHz), the available bandwidth of the antenna covers the 2G/3G/LTE bands, and the antenna obtains a stable gain that the average value is 10 dBi. Meanwhile, the antenna has good performance in radiation characteristics. The proposed antenna can be applied to the base station communication systems.

A coupling theory based on characteristic modes is developed to help enhance the bandwidth of an antenna. And two important concepts, namely source-mode and mode-mode couplings, are proposed to form a core of our coupling theory. We use a dipole which loaded by lumped reactance to validate the theory.

A low-profile end-fire phased array with omnidirectional scanning characteristics is presented in this paper. The antenna consists of novel omnidirectional radiating elements to realize 360° scanning in azimuth plane in over 20% bandwidth (VSWR<2), while the total height of array is only 0.054λ0 (λ0 denotes the free-space wavelength corresponding to the center operating frequency). An 8×8 finite array is simulated using commercial software to validate the performance of the finite array. The edge effect of the finite array is discussed. Numerical results show that the proposed low-profile end-fire phased array has good omnidirectional scanning characteristics in azimuth plane.

In this paper, three kinds of SIW 2 × 2 slot array antennas excited by TE20 mode are designed and analyzed. According to the field of 2 × 2 point sources array and the characteristics of TE20 mode in SIW, the slots are positioned properly to obtain proper radiation. Then, stimulated by a power divider with 180° phase shifter, SIW slot array antennas excited by TE20 mode are simulated. The results indicate that all have good directivity and the radiation performance declines as the angle between slots and center line of SIW increases.

This paper presents 130 GHz on-chip dielectric resonator antenna (DRA) arrays using a standard CMOS technology. The half-mode cavity feeding structure is used to excite the dominant and higher-order modes (TExδ11 and TExδ13) of the dielectric resonators (DRs) in the antenna design. The 2 × 1 and 4 × 1 arrays have been both investigated with the proposed antenna element. The 2 × 1 arrays with TExδ11 mode and TExδ13 mode DRs achieve the measured peak gain of 6.3 dBi and 7 dBi at 134 GHz, respectively. The 4 × 1 arrays have also been demonstrated to be 7 dBi gain with TExδ11 mode DR and 8.2 dBi gain with TExδ13 mode DR. Moreover, the arrays have the 3-dB gain bandwidth of ∼ 10%. In the silicon-based on-chip antenna array design, the suitable number of array elements is 2 to 4. More array elements would not increase the gain obviously while occupying lager chip area.

Over-the-Air signals, generated within an anechoic chamber are being utilized for testing Massive MIMO antenna array systems. Multiple probe antennas emulate distinct propagation paths within the field of view. Static environments have been suggested, however a moving cluster concept is described using multiple probes to emulate motion in a Massive MIMO test scenario. A channel emulator is utilized to emulate the bi-directional channel model between the Massive MIMO array via chamber probes and one or more UEs. This approach supports multipath channels having potentially different motion assumptions for each propagation path.
